well it is too much, cruise is complex and testing while driving it is crazy dangerous.
the way it works is simple but not how it was deployed, (no diagnostics modes at All) <<< REAL BAD THIS IS TO ANY TECH,
i have portable data loggers (voltmeters ) that allow me to test on the road any test point. (and same for noise (electronic stethoscope)
the VSS on this car there are 2,
1 in the transmission tail shaft RPM speed sensor that is used by the TCM (tranny 4speed brain shifter)
2; and one in side the speedo cluster, seen on my huge cluster page. speed head VSS1

if the car is not moving or too slow or too fast , CRUISING IS DISABLED. (both are unsafe acts so are dis ALLOWED)
the test for these sensors is on jack stands, (safe) and driving the car, in gear,
but YOUR VSS is not dead, either,
because the OD lamp on the 4speed will go nuts telling you it is failing, VSS2 (tranny)
and VSS1 dead will fail for ECU DTC error 24, VSS1 is dead. (speedo cable snapped is why)
This is not easy , nothing is more hard really, and very very rare documents, most manuals I have (scads) have no CRUISE PAGE AT ALL.
working on any undocumented device like this is not easy.
first would be the brake switch it must have the dual switch.
seen many cars the owners had this fail and replaced it with the wrong switch not the cruise version
just only look under dash is first. it is there or not there, 2pins/wires wrong 3 or 4 pins/wires correct.
look for missing parts wires and plugs to all parts of this cruise option.
the inputs to cruise are first, (after all any logic or computer is the same rules) input must be correct. or GIGO happens, garbage in , nets you garbage out.
I gave up finding books on cruise, only one 96/98 version I have, and not same here i think.
is the cruise motor box next to the TB , throttle body present and its cabl motor drive to the TV throttle valve present.
